FAN ATTACHMENT F OR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 245,376, dated August9, 1881.

' Application filed June 3,1881. (No model.)

To all whom it may concern:

Be it known that we, PETER HEBNER and CHAS. W. ARMSTRONG, of Boonville,in the county of Warrick and State of Indiana, have invented certain newand useful Improvements in Automatic Fans for Sewing-Machines; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawin gs, and to letters of reference marked thereon,which form a part of this specification.

Our invention relates to an improvement in automatic fans, the object ofthe same being to provide a fan with suitable attachments, whereby itcan readily be attached to a sewing-machine to fan the operator and bedetached therefrom when not required for use.

With these ends in view our invention consists in certain details inconstruction and combinations of parts, as will be more fully explained,and pointed out in theclaims.

In the accompanying drawings, Figure l is a side view, showing ourdevice attached to a sewing-machine; and Fig. 2 is detached perspectiveview of the fan and connecting mechanism.

A represents a suitable standard having the clamp B at its lower end, bywhich it is attached to the sewing-machine table, and a fanlever, O,pivotally secured at its upper end. The fan-lever G is provided with afan-holder, D, at one end, having a central opening, into which thehandle of the fan is introduced, and a thumb-screw, E, to retain the fanin position, and is pivotally secured at its opposite end to thefan-pitman F, the latter extending down a suitable distance and providedwith a ring, Gr, by which the fan is connected to the pitman of thesewing-machine and caused to opcrate when desired. 7

H is an arm having screw-holes I at one end, by which it is screwed tothe sewing-machine pitman J, and a spring-holder, K, on the top thereof,with which the ring G, on the end of the'pitman F, engages. This arm Hisadapted to be screwed or otherwise secured onto the pitman J and extendout backward nearly at right angles to the pitman J, with thespringholderK on the top. This holder can be of any desiredconstruction, and instead of being made of spring metal can be a simplehook or any suitable device; but the construction shown answers all thepurposes admirably, as it holds the pitman Fin close contact with thearm H and prevents any unnecessary movements of the said pitman F. Thisspringholder is constructed of metal, bent substantially as shown in thedrawings, with one end bent at right angles to the remaining portion anddriven into the arm, which, together with the staple Ii, keeps theholder well down on the upper surface of the arm. That portion of thespring-holder adapted to bear directly on the ring G is slightlyrounded. which allows the ring G to rest therein, while at the same timeit prevents any unnecessary movement of the said pitman, which wouldcause irregularities in the movement of the fan, and the outer or freeend of the holder H is turned upward, which allows the ring G to beslipped under the turned end of the holder and slid into properposition. I

When the parts have been secured in position and motion imparted to thesewing-machine the fan is also caused to vibrate up and down in unisonwith the pitman of the sewing-machine, to which it is secured. When itis desired to remove the fan from the machlne it is simply necessary toloosen the clamp B and remove the ring Gfrom the spring-holder K, whenthe device can be taken from the machine, it not being necessary toremove the arms H unless it is desired to transfer the fan to some othermachine.

The device is exceedingly simple in construction, of small cost, andadapted to be readily attached to and detached from any sewing-machine,aud agreat many other machines without extra cost or any increase ofpower required to operate it.

We are aware that fans have been connected with and adapted to beoperated by the dIlV- ing mechanism of sewing-machines, and hence wemake no broad claim to the combination, with the driving mechanism of asewing-machine, of a fan attachment adapted to be operated thereby.

Having fully described our invention, what we claim as new, and desireto secure by Let- In testimony that we claim the foregoing we 10 tersPatent, is have hereunto set our hands this 21st day of The combination,with the standard A, fan- May-1881.
